Tools like that work up to a point. How well they work will
depend greatly on the Mathematica code you've written. If that
code makes extensive use of built-in functions such as say
DSolve or NDSolve, these tools won't be very useful too you.
Simply put, you cannot expect any of these tools to output C++
code for specialized Mathematica functions.

It isn't the overall application that matters. It is the
specifics of what functions you use that matter.

Understandable since this would not be a trivial undertaking
especially if you have to re-implement something equivalent to
Mathematica's NDSolve or some other specialized function.
